Quick questions on DNA sequencing and genetic profiling: O-Level Genetic Engineering Techniques
5short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is dNA sequencing?Show answer
DNA sequencing reads the exact order of bases (A, T, C, G) along a piece of DNA.
What is genetic profiling (DNA fingerprinting)?Show answer
Genetic profiling does not read every base. Instead it compares particular regions of DNA that vary a lot between people, called variable regions.
What is q1?Show answer
State what DNA sequencing determines. [1 mark]
What is q2?Show answer
Explain why a genetic profile is different for almost every individual. [2 marks]
What is q3?Show answer
Give one use of DNA profiling. [1 mark]
